Sample Variance
A statistic that measures the dispersion of a sample dataset, representing the average of the squared differences from the sample mean.
Population Variance
Population variance is a measure of the spread between numbers in a data set, representing the average of the squared differences from the population mean.
Random Sample
A selection taken from a group where each individual has the same probability of being chosen.
